Here's a study (Error - Cookies Turned Off) that did not find a difference in the amount regained after 9 months between a low-calorie diet (LCD) group and a very low calorie diet (VLCD) group. The LCD group lost weight at a rate of 0.7 kg/week and the VLCD group rate was 1.8 kg/week. The LCD group ate 1250 kcal/day and the VLCD group ate 500 kcal/day.
My rate is 1.9 kg/week and I'm eating about 2000 kcal per day with exercise.
I think there's more out there so I'll keep looking. It's anything but clear. I understand the general advice and it's good - go slow - but it seems the reasoning is intended to change behavior and diet sustainably over the long term and doesn't necessarily mean that the actual rate determines whether you'll gain it back.
